LG to show 55-inch OLED TV at CES

Each January the Consumer Electronics Show (CES) is the venue for consumer electronics companies to unveil their upcoming goods as well as some milestone products. This year LG Electronics plans to show the world's largest OLED TV - a 55-inch display that's just 4 mm thin and weighs a mere 7.5 kg.

The new HDTV uses advanced OLED (organic light-emitting diode) technology with "4-Color Pixels and Color Refiner" features that generate natural, accurate colors without jaggies and other imperfections. With the 4-Color Pixels feature, each pixel uses a set of four colors - red, green, blue and white - which expands on the common RGB (red, green, blue) setup. The TVs are also 1,000 times faster than LED/LCD displays according to LG.

OLED is a carbon-based technology that uses thin films of organic materials between two conductors to transmit an image and requires no backlight to project a bright image. The technology was originally limited to smaller displays such as MP3 players, cell phones and devices with small screens. Technology advances have now allowed for TV sets using OLED technology. Although they look fantastic, the small selection of OLED TVs that have entered the market in recent times haven't exactly set the world alight in terms of sales due to high prices when compared to the alternatives.

The Korean consumer electronics manufacturer will also use CES to unveil its 84-inch Ultra Definition set, which has 8 million pixels.
